Common Questions
Yes, 100%. FileForge uses browser-native APIs (Canvas, FileReader, Blob) to process everything client-side. Open your browser's network tab during conversion — you'll see zero outgoing requests. Your files never leave your device.
There's no artificial limit. The practical limit is your device's available memory. Most modern devices can handle files up to 500MB+ without issues. For extremely large files, we recommend converting in batches.
Images: PNG, JPG, WEBP, BMP, GIF, SVG, ICO, DDS, TGA, AVIF. Documents: CSV, JSON, XML, Markdown, HTML, TXT, YAML. We're continuously adding more formats based on user feedback.
Yes. Switch to "Batch Convert" mode, select multiple files (or drag a folder), pick a target format, and convert them all in one click. Results are downloaded as individual files or a ZIP archive.
After the first page load, FileForge works entirely offline. You can even bookmark it and use it on a plane. No internet connection is needed for any conversion.
Not at all. We use native browser encoding with configurable quality (1–100%). For lossless formats like PNG, the output is pixel-perfect. For lossy formats like JPG and WebP, you control the exact quality level.
